Does this really solve the ethical wicket of human embryo testing? Is tricking stem cells into forming an embryo really that different from fertilizing an egg with a sperm cell to form an embryo? Like, would this still develop into a functional human being if implanted into a womb?
The article says the embryo models have a 99% failure rate, and also that it would be impossible to achieve pregnancy with it. Sounds like the process to coax the cells to form an embryo and miscellaneous parts takes too long.
